- infra/compose/dapr.yml: Dapr placement service for sidecar coordination
- infra/dapr/: Dapr global config, pubsub component (NATS), statestore (Redis)
- infra/compose/scraper.yml: add Dapr sidecar container + depends_on nats/dapr
- docs/add-dapr-service.md: guide for integrating Dapr into new services
- docs/add-new-app.md: add Dapr sidecar step
- ARCHITECTURE.md: add NATS/Dapr to infra table + service mesh diagram
- infra/README.md: update layout and deployment order
